In the content strategy tool, a topic cluster is an overall grouping of a core topic (pillar page), subtopic, and linked content that helps establish authority for a specific topic. Learn how to create a topic cluster below.

Create a topic cluster and add pillar content

• In your HubSpot Marketing Hub Basic, Professional, or Enterprise account, navigate to Content > Strategy.

• In the upper right, click Create a topic cluster.

• Click Add core topic in the center of the topic cluster to add your core topic. Once you key in a core topic phrase, metrics for how you would rank for this topic in domain authority and monthly searches will automatically be generated.
• Alternatively, you can select a core topic in the Suggested core topics section by clicking the radio button next to a suggested core topic.
• Click Save at the bottom to add the core topic.

• Click Add pillar content under the core topic to attach a pillar page to your core topic. A pillar page should be the authoritative source your related subtopics will link back to.
• Under Select pillar content, click Create a landing page to create a new landing page, Add external URL to link to an external resource, or use the Search for content search bar to search for and select an existing landing page.
• The Most Relevant Content section will automatically display content that is most related to your core topic for you to choose from.

• When you're done, click Save at the bottom.

Add subtopics and supporting content

• Click Add subtopic to add a subtopic to the topic cluster. Once you enter a subtopic phrase, metrics for the average monthly searches for the subtopic and core topic similarity will automatically be generated.
• Alternatively, you can select a subtopic in the Suggested subtopics section by clicking the radio button next to a suggested subtopic.

• To hide suggested subtopics and improve future suggestions, hover over a suggested subtopic and click the Hide dropdown. Select the radio button next to the feedback you'd like to submit, then click Hide suggestion.

• Click Save at the bottom to add the subtopic.
• Lastly, add supporting content to your subtopic. Supporting content is shorter in length than pillar content and helps build authority around your core topic. 

Please note: each piece of supporting content can only be attached to one topic or subtopic in the content strategy tool.

• Under Select supporting content, click Create a post to create a new blog post, Add external URL to link to an external resource, or use the Search for content search bar to search for and add a HubSpot blog post, landing page, or website page.
• The Most Relevant Content section will automatically display content that is most related to your subtopic for you to choose from.

• When you're done, click Save at the bottom.
